2. APPLICATIONS

1. The Neschen large-format laminator is intended for applying laminating and backing foils using either pressure or heat to activate an adhesive layer to large-format prints, plates, boards and similar products whose width does not exceed 1650 mm.

2. Although the laminator is designated as a large-format device, it can be also used for laminating smaller formats, starting from A5.

3. Maximum length of laminated prints is not limited by the laminator’s construction.

4. Larger formats (greater than A0 or equal to the device’s maximum working width) may require

the help of another person.

5. The Neschen laminator’s simplicity and flexibility is based on its ability to work with cut material (sheets), cut from material in rolls. The user has a unique opportunity to choose a laminating technique. Either sheet lamination or from-roll lamination or roll-to-roll lamination.

6. Any changes made to this laminator without the manufacturer’s permission will relieve the vendor from its liability for any damage or injury!

7. If the laminator’s features allow the device to be used for other purposes not listed here, the user must consult such application with the vendor.

8. When working with the device, abide by the provided safety guidelines to avoid injuring yourself or other persons around you.

9. Those instructions which require special attention are in the User Instructions identified with the following safety symbol:

5. MAIN SWITCH – POSITIONS

OFF - the laminator is switched off.

ON - the laminator is switched on.

PRESSURE SETTING KNOB – setting the knob to the required position sets the main roller pressure. In the down position the pneumatic system pushes the main roller down by applying the force from 1000 up to 4500N. In the up position, the pneumatic system automatically reduces the main roller pressure to 500N.

6. CONTROL PANELS- RIGHT

Emergency STOP button – it has the identical function as the one on the left control panel.

The top roller can move up and down. The gap ranges from 0 to 40 mm.

Please note: the roller lift functions only if the rotation direction run or rev has not been selected (the direction button is not lit). The roller lift is controlled by the following buttons:

down – the top roller moves down. The button must be held depressed. When released, the roller stops moving immediately. When the top roller touches the material or the bottom roller, it stops automatically, alerts with sound and lights and the machine will not allow further down movement – it will only allow up movement. If during down movement a light beam barrier is interrupted, a warning buzzer will sound but the roller continues to move down.

up – the top roller moves up. The button must be held depressed. When released, the roller stops moving immediately. When the roller reaches the 40mm maximum, it stop automatically, and the machine will allow only down movement.

Roller rotation – the bottom roller is driven by an electromotor. Its revolutions can be continuously controlled within the range from 0 to 8 m/min on ColdLam and 12m/min on HotLam.

The rotation Turn knob – a speed control potentiometer by which the required speed is set in meters per minute.

run – to select roller rotation for forward movement – the rotation direction is indicated by the button lighting up. The Neschen laminators have an advanced intelligent start-up function, whereby the laminator starts up gradually and smoothly until it reaches the exact speed set by the turn knob - the speed is

independent on the load. Please note: If the roller rotation speed is set to 0, the laminator will not start up but wait for the operator to set a non-zero speed.

If the machine is equipped with a footswitch, stepping on the footswitch will make the

machine move in the run direction at speed of 1m/min with warning buzzer sound and

ignoring the light barriers.

slow – the back control panel works the same way as the footswitch. When pressed the machine move in the run direction at speed of 1m/min with warning buzzer sound and ignoring the light barriers.

rev – selects the rollers to rotate in the reverse direction (otherwise it functions identically as run).

stop / settings – stops the rollers from rotating and cancels the rotation direction. If, while the machine is running, the light beam barrier is interrupted, a warning

buzzer will sound and the machine will stop. Please note: If the operator wants to change the rotation direction while the machine is running, the operator must first press the stop button and only then select the required rotation direction.

To enter the settings the operator has to press and hold the stop / settings button for three seconds.

The operator is now able to adjust the temperature by pressing the UP / DOWN button after pressing the stop button the operator will reach next menu point.

9

To reset the Odometer ( daily counter ) the operator has to press once the UP / DOWN button.

To run the Machine with a fixed distance the operator has to choose the distance in Countdown Menu in full meters. Machine will stop then afterwards automatically.

IMPORTANT: If the operator would like to run afterwards without automatic stop, he has to reset the Countdown to zero.

Standard Pressure for single side laminating ( Print and Film ) is 1,5 bar ( +- 0,5 bar )

7. SILICONE PAPER AND LAMINATED PRINT

Shaft rotation – the silicone paper and laminated print (finished products) shafts are driven by electromotors. The machine synchronises their revolutions with the rotation speed of the main rollers. Print, laminate and double-sided page release liner shafts are braked. Resistance on all shafts can be changed by turning the heads of control bolts. The more the bolt is tightened, the more resistance the shaft puts up, and vice versa.

8. FUSES AND FOOTSWITCH CONNECTOR

The Neschen laminators have three fuses. Their parameters and how to replace them is described in section Maintenance and Repairs. The connector is used to connect a footswitch.

9. ROLL CARRIER

Laminating materials as well as printed materials are wound on paper tubes of an internal diameter three inches (76,2mm). The Neschen laminator shafts are designed for these tubes.

If the laminate being unrolled from the shaft is too slack or too tight, the braking force can be adjusted by turning the head of the bolt on the right hand side of the machine. By tightening the bolt the braking force is increased, and by loosening it the force is reduced.

10

If silicone paper fails to wind up, winds up too loosely or too tightly, the shaft resistance can be adjusted by turning the bolt on the right hand side. By tightening the bolt the resistance is increased, and by loosening it the resistance is reduced.

10. INSERTING A ROLL OF MATERIAL ONTO THE SHAFT

1. Remove the shaft from the laminator. Shafts are fastened in the laminator with locks on the right hand side. Turn the carrier until the lock is released. Positions for materials which are under the table have their shafts secured with a turn lock. Before removing the shaft, the lock must be released. Remove first the shaft on the side of the lock.

2. Insert the roll of material onto the shaft. When handling heavy roles, it is advisable to have another person.

3. Replace the shaft back onto the machine in a reverse procedure to the one described in point 1.
